Hi @g7777, although as a last resort you may reinstall 10.5.10, this version of Tor Browser is outdated and is missing important security updates.
As such, where possible, we would strongly recommend continuing to use Tor Browser 11.0.1 with any of workarounds identified in the tickets above while we work on fixing the Windows issues (for example: using Tor Browser without additional add-ons or extensions).
Thanks for your patience!
