Bitwarden.exe stopped opening/running on Windows 11, does not appear in programs list only in folder

Hi, Have been using desktop version on Windows 11 for more than a year. The desktop app stopped running since last week. Cannot run the exe file from folder either. I want to try a clean reinstall but I cannot see the app running in Task Manager or Programs list. Exe version is 23.9.10 and last modified 10th Oct.
The PC had major slowdown around the same date but no malware was detected. I did run a disk cleanup though. Did I end up deleting any required files.

Looking for tips to do a clean recovery or reinstallation if possible. Thanks.

Maybe check if Windows Defender is blocking it from running.

Also, go to Control Panel\All Control Panel Items\Programs and Features, and look for Bitwarden there. If you find it, select it, and then click “Uninstall”.
