LR 13.5 Often freezes on export

[PagiArt]

After updating to 13.5, Lightroom often freezes when I try to export more than ~10 photos with watermark. I need to do many exports of 10 photos instead of one with for example 25 photos. Is there any fix for this?

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 out as that is just so much dead space to us non-Techs and it takes up vast amounts of scroll space making the reply less readable and less likely that others will bother with your post.

And please post a screenshot of your LrC /Preferences/Performance/

And your hard drive that your catalog is on, how much free space in percent? Looking for at least 20% free, some say 25% free.

[PagiArt]

About 30% free. My SSD drive is okay and it's definitely problem with Lightroom, not hardware.

Does disabling "real time protection" in windows defender make a differance? Been having similar issues when importing recently that seems to have cured mine.

[PagiArt]

I don't use Windows Defender as antivirus, so it isn't enabled.

[Gixxxa75]

Yeah, I use third party anti virus and thought defender was diasbled as well. not sure if both were running at the same time causing issue. Even unistalled the third party antivirus as I suspect it was the issue, but windows defender kicks in as soon as you uninstall the third party one.

Try turning off the GPU in LrC before you do the export.

Please provide the system info as requested by @GoldingD 

Also, a stated by @Gixxxa75 turn off you anti-virus to see if it helps.

I tried turning off GPU in LR and although it didn't fix problem with Lightroom, it gave me bluescreen on which there was some important info for me. I have 13th gen Intel CPU and maybe you have heart that there is a lot of problems going on with latest BIOSes for them. Lightroom was crashing because of unstable CPU. I thought that mine is stable as I tested its stability in other apps, but it looks like LR is a bit different case. I tweaked some BIOS settings and now it's working like it should, but I need to work again on CPU temperatures. Problem solved, it's Intel's fault.

Do you remember what that error message stated. I think I remember something on the web about such a screen that would indicate your CPU and BIOS were at risk of the Intel issue. (but currently having an issue searching for)

And did you visit your computers or Motherboard support site for an updated BIOS? (one that addresses the Intel CPU issue)

It was "clock_watchdog_timeout". I already had updated BIOS about a month ago, but the thing is that these new BIOS versions aren't just "update and forget". I had to disable IA CEP and tweak SVID Behavior, because without that CPU was overheating on high load. I set SVID Behavior to "Best-Case Scenario" and had low temperatures, but now it turned out that in Lightroom PC is unstable. So today I changed SVID Behavior to "Typical Scenario", temperatures rised to 94 degrees on high load, but at least CPU was stable. Next I did undervolting and so far it's running stable with about 89-90 degrees on high load.
