Hey, @raoulh60245238. Welcome to the Lightroom Community. I couldn't find crash reports submitted with the account you've signed in to the community with. If you see a crash dialogue, submit it with your Adobe ID. Check here for more steps: https://adobe.ly/3Wpjx0B

If Lightroom crashes when using specific tool sets such as Denoise, Masks, or Enhance, it could be a GPU-related issue on Windows. For now, follow the steps here to troubleshoot the GPU: https://adobe.ly/4aNMIjk

The ThinkPad T1g Gen 8 has 2 GPU adapters, the embedded Intel Arc 140T & a Nvidia GPU based on the product specs. Try these steps to get Lightroom to behave as expected:

1 - Update the graphics drivers using Intel's & Nvidia's auto-detect programs.

2 - Follow step 6 in the content here to configure the default GPU for Lightroom: https://adobe.ly/3QQQWB8

3 - The Steps are for Photoshop and Sniffer; for Lightroom, please follow the steps, and add lightroom.exe to the list.

You can also monitor the Windows Event Viewer > Windows Logs > Application Logs to check for error reports and share them here. 

Let me know how it goes. Thanks!
