Lightroom Classic 2023 crashing Windows 11

All fixed.  The graphics driver has a utility that can customise it's behaviour by application.  Lightroom is one of those applications.  

最近のバージョンで、クラウドとの同期が有効になっていると動作が重くなりクラッシュする事がありました。もし、有効になっているなら同期をOFFにしてみてください。

Lightroom以外の不確定な要素として、セキュリティソフトが悪さをしている事も考えられます。

使用している場合は、一時的にOFFにしてどうなるかを試してみてください。

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.

In a first step you should try to reset the Lightroom preferences.

It's recommended to backup your preferences before you reset the preferences to the default settings:

If this doesn't help I would suggest a complete and clean reinstallation.

Please follow the steps below:

• backup all personal data, like templates, presets, catalog(s) etc.
• uninstall everything cc including preferences,  https://helpx.adobe.com/creative-cloud/help/uninstall-remove-app.html
• then uninstall the cc desktop app,  https://helpx.adobe.com/creative-cloud/help/uninstall-creative-cloud-desktop-app.html
• clean your computer of cc files per http://www.adobe.com/support/contact/cscleanertool.html
• restart your computer (don't skip this)
• reinstall the cc desktop app,  https://www.adobe.com/creativecloud/desktop-app.html
• use the desktop app to install your cc programs/trials
• restore your personal data.

If you're unable to install the cc desktop app at this stage, use an administrator account (solution 4 here,  https://helpx.adobe.com/creative-cloud/kb/creative-cloud-missing-damaged.html)

Did you see a crash dialog?

Do you use a different email address when filling out the crash report?

Was the crash dialog Adobe’s? Microsoft’s? 

I find it odd after 41 years in IT that your assumption in your first paragraph would be correct particularly if only one application and numerous forums reporting this issue.  Nonetheless, the laptop window OS is upvto date.  I've ran a DELL hardware diagnostics - no issues, (particularly the fans).  The graphics driver is the latest.  Can't load LrC long enough to create a system info, however no issue wityh Photoshop which is stable.  Reports available here.

If the entire computer crashes, that is either a bug in the operating system, a bug in a graphics driver, or a hardware problem.  LR uses a computer much differently and more intensely than other apps, so it's not unexpected that LR would trigger an OS/driver bug or hardware problem more frequently than other apps.

Troubleshooting steps:

1. Update the graphics driver by going directly to the manufacturer's web site:

2. After updating to the latest driver, do the LR menu command Help > System Info and copy/paste the entire contents here so we can see exactly which versions of hardware and software LR thinks you're running.

3. It may be that the cooling system is not working properly, e.g. the fans are clogged. There are many reports here over the years of LR triggering overheating (but not other apps) because LR uses the processor more intensely.  Download the free Intel Power Gadget and monitor the temperature:

4. Run hardware diagnostics, e.g.
