The new release 7.0.19 did the opposite for my system (Windows 10 Pro 22H2 build 19045.6036); after the upgrade, Zotero failed to start its GUI. It only ran as a Windows process.
Re-installation did not help (after killing the process), so I had to downgrade to 7.0.16 and all works fine again.
This is the first time I experienced any issue with Zotero and I work with it on a daily basis.
If so, see Reporting Startup Errors for what we'll need to debug this. If the debug output window doesn't appear either, see Logging to a Terminal Window and copy or take a screenshot of the console window when it freezes.

NB: I start Zotero with profiles to add different libraries from different storage locations I created.
