P: Hanging, requires force quit

Yes, you hit the nail on the head.  It's the nothing communication from Adobe.  Still have problem here. 

Mine only occurs when I leave it alone for a couple hours, then it has to be killed.  My sort of workaround is to close it when not using it but inevitably forget and have to kill it. 

I really appreciate the communication from Victoria and it's been amazing to watch her gracefully deal with difficult people on this thread.
Still adobe is failing bad on communication, it's just super frustrating, I keep thinking they'll release a fix any day and surely they will but this is ridiculous to not tell anyone publicly anything.

I dont want to dissuade anyone from posting their concerns and problems, but I believe the USB connectivity issue causing problems is a separate issue from the hanging problem this post was created for.  I can unplug and plug in whatever i want and get no problems, but i still get random and regular hanging of the program.

Also, some of the frustration with this, is that it has been going on since the DAY the new update was given out and we have gotten no official response.

Yes we roll back and keep going, but at the moment there is no guarantee that this will get fixed nor that the next update will even address it and potentially might even make it worse.

I accept software glitches and time is needed to fix them, but there is NOTHING wrong with telling us what is going on and a general timeline for communication on the progress if not a general timeline.

This is not a feature problem or slowness complaint, this is a total application failure event, which is not small nor something that shouldn't be addressed immediately.

This has gone on for over a month now with nothing official said.  If they want to keep it private FINE, but give us an option to contact them directly and privately to learn the progress and troubleshoot. Not just vague forums with no guarantee of help.

Since the last update CC classic 7.3.1 ; when i input a new CF Card  with lightroom already open => lightroom freeze and i can't make anything. 

I must reboot lightroom ( ctrl + alt + sup ) 

config: 

windows 10 64 bits last update 1803
intel core i7 + 32 Go Ram. 
SSD for system and catalog and raid disk for the raw. 
CF Card Reader : Sandisk usb 3 imagematepro reader
CF Sandisk Extreme 64 Go 120mb/sec

For now, I would say the best option is to roll back to version 7.2 and wait for a fix to be released.

The same problem here, crashes about every 10min. Very hard to do a good job like this. I noticed there is a link with inserting/ejecting usb drivers. Every time I connect or disconnect my phone, Lightroom crashes. The same with thumb drives.

Adobe developers can you tell me which module (dll file) is used for importing photo's from usb drives? So I can just delete that file, I never use the import dialogue any ways. I remember some years ago the same bug was there, and deleting that file worked for me as a solution. I just cannot remember which file it was. Please tell me so I can do my job instead of waiting ages for Adobe to come with a solution.

Like the rest that have spoken on this tread, my PC encounters problems with LR 7.3.1 hanging up and becoming "Not Responsive". I have rolled back to LR 7.2 which performs fine. I have tried updating my drivers, GPU on / off, increased RAM, etc. Nothing seems to help the LR 7.3.1 hang up problem. Clearly with 7.2 performing perfectly but 7.3.1 crashing, it appears to be a LR version specific software problem. 

Totally agree! We need a fix. 

Hear, hear!

Adobe (if you are listening) please release this fix ASAP for two reasons:
1) To end our unbearable frustration because of this bug!
2) To bring an end to pointless conversations in this thread!
