Since June 3rd or 4th, 2021, I've been getting an error message when photo editing in Lightroom Classic. It usually happens if I click in a command without waiting for the previous command to finish up. Lightroom crashes and Microsoft sends the message: VIDEO_DXGKRNL_FATAL_ERROR, before shutting off my pc..This issue started only after Lightroom was adjusted or updated overnight with tutorials added. My previous settings had been erased. I was not having problems until the June changes. Restarting my pc would allow me to reopen Lightroom and continue working, but another problem has come up - the message that Lightroom cannot be opened because the catalog is already in use. The VIDEO_DXGKRNL_FATAL_ERROR can be due to a number of causes but it coincides with the recent Lightroom update. Is there any way for Adobe to correct for the bugs in that update? At present, I can no longer access Lightroom Classic.
Follow-up on problems: A post from several years ago, helped out on the "catalog already in use" problem. Searching my pc for lightroom files with a .lock ending and deleting the most recent, ermitted the start up of my Lightroom Classic.
The other issue, that originally caused the crash, remains open. My pc may require newer drivers or I simply may need a new pc.
It would be a good idea for you to delete all lock files. If LrC shuts down properly there should never be a lock file left behind. What operating system are you using, and how much RAM does your computer have?
I'm using Windows 10 with 16 GB RAM. My pc is about six years old, so it is approaching the end of its life span. After deleting my .lock files, I also got a notice from Adobe that said my Creative Cloud was corrupt and offering repair. I did so. So far, no further crashes. Time will tell.
Update of June 5th, 2021. The repair of Creative Cloud seemed to work out, but the Blue Screen of Death reappeared; this time with DRIVER_IRQL_NOT_LESS_OR_EQUAL No lockout happened; but, when using Lightroom Classic, and its brush, no pin marker appeared. It may be that the early June update of Lightroom was too much for my graphics card or driver. Continuing to explore.
Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.
Typically, this error occurs whenever there’s a corrupt driver that interferes with the normal functionality of the GPU.
Got that info by googling VIDEO_DXGKRNL_FATAL_ERROR
So, what GPU? (my previous request will show that, in fact the main reason for the sys info request)
Thanks. Here is the system info:

I did attempt to update the driver, but got a message that my driver is the most up to date. I will wait to see if there are any more crashes.
>>I did attempt to update the driver, but got a message that my driver is the most up to date...
In this case I would try a former version of the driver. Sometimes the latest versions are buggy.
What has been changed on your system before the error occur?
The only change I noticed was an update by Adobe Lightroom that added tuorial aides to Lightroom. Unfortunately, this also erased settings that I had previously made on various controls - for example, the pin marker when using the brush control. I had it set for always, the update removed this. Also, preset demos normally would appear when passing the cursor over each. That was changed as well. While trying to photo edit and re-personalize my Lightroom, the first of numerous crashes occurred. Lightroom seemed sluggish and much more likely to crash with the Blue Screen of Death if it had been left on with no ongoing activity, and then activity resumed later. Going back to a prior Driver that worked ok is a good idea, but the existing driver has been present since August 2020 with no problem until June 2021. Also, I see no command to revert to an older Driver. Uninstalling and then re-installing might be another way, but I'm no techie so I'm reluctant to get in over my head. There's been no crash today that I know of, although the pc seemed to have gone through a restart overnight. Thanks for the ideas.
Graphics Processor Info: DirectX: NVIDIA GeForce GT 640M (126.96.36.19909)
So v369.09. That is not the current version. From
that would be v425.31. Mind you fairly old (4/11/2019) on that very old GPU
You should have a NVIDIA utility called GeForce Experience. Use that to update the driver (make sure GeForce Experience is not out of date)
Thanks for the info on the Driver v425.31 and the GPU. No crashes in 24 hours. Have found that resuming Lightroom activity, having left it running without use, seems to cause an "overload" - then a freeze - then a crash. Closing Lightroom between uses appears to avoid the problem. From your info, it seems appropriate to move on to a new pc. Thanks again.

so, not 4K, and an old GPU. If you have the use GPU option enabled, disable that, sub 4K it is not of much help, and a GPU that old (800 series and old have this issue) very buggy when enabled sub 4K, can actually make things worse.
Just for the record: blue screens are never a user's program (like Lr) issue, but always OS related: either Windows itself or what is mostly probable a buggy driver. Even if Lr does something wrong, it's the task of the OS to catch that and to send back an error. So, the solution is to investigate drivers (in this case the screen driver) and to hope that the driver supplier gets this sorted out.
Thank you. I did get another crash that was unrelated to Lightroom activity. Lightroom was closed and not in use.
