Judging by the error in your system info, there might be some issue with Cycles or your user preferences. It fails to write the Cycles section properly where the compute devices should be reported:

CPU device capabilities: SSE2 SSE3 SSE41 AVX

OpenCL device capabilities:
No OpenCL platforms found
ERROR: malformed node or string: <_ast.Str object at 0x7f797a700fd0>

Please start a terminal and navigate to Blender's directory. Start Blender with the following command to create a debug log in your home directory.

./blender --debug --debug-cycles > ~/blender_debug_output.txt 2>&1

Try to open the user preferences again, then close Blender. Add the debug log to your bug report by clicking on the upload button as shown in the screenshot below or via drag and drop.

Please also try to start Blender with factory default settings through the following command and check if the user preferences still don't display properly.

./blender --factory-startup

Avoid saving the preferences when starting with this option though as it will overwrite your existing ones.

Your log file contains a permission error, that yjd is not in the group of sudoers. It seems that you've accidentally changed the permissions on the directory where the add-ons are stored or files within and Blender is unable to access them. Perhaps this occurred during the installation of an add-on.

As a quick test to verify that this is the cause, you can rename the $HOME/.config/blender/2.90/ directory to e.g. 2.90-orig and download the portable version of Blender (.tar.xz). Extract in a directory of choice and start it. You should be able to access the add-on preferences. The even quicker approach would be to start your current Blender installation with sudo but that is not recommended for security reasons.

I would suggest that you check the permissions of the original, now renamed, $HOME/.config/blender/2.90/ directory and files within and make sure that your user is allowed to access them. You can change its name back to the original once you've resolved the permission issue with chmod.

I spotted the last add-on installed in . config and I deleted it. it works again. Thank you

photogrammetry_importer.zip : It was a zip that I made from the contents of this zip here, so it would fit into Blender Blender-Addon-Photogrammetry-Importer-master.zip ; finally I don’t understand how to install it, so I think I’ll drop its installation.

The __init__.py of the add-on uses an incorrectly formatted bl_info. There should be no string concatenation with + happening.
