I am not a tech pro. When the forums mentioned uninstalling lightroom for crashing issues, I did. I thought I could reinstall easly on my adobe account ...no. I have a life time purchase code, just no link to reinstall,
If you have installed many third-party plug-ins and are experiencing odd behavior in Lightroom Classic, troubleshoot the plug-ins next.
Check with the plug-in manufacturer to see if they have an update for your plug-in. Disable problematic plug-ins using Lightroom Classic's Plug-in Manager: In Lightroom, choose File > Plug-in Manager. Click Disable for each of the listed plug-ins. Check if the problem is still occurring. If the problem is resolved, turn the plug-ins back on one by one. Check to see if the problem reoccurs after re-enabling each plug-in.
