Problems with KB5033375

After installing the newest Windows Update KB5033375 Rainlendar did not autostart any longer. I could start it manually but I had a rainlendar-command something in my taskbar. Closing that caused crash of rainlendar.
I had to deinstall the update…
Any Ideas?

That’s strange. I installed KB5033375 on my laptop but I did not notice any problems with Rainlendar.

Have anyone else have experienced problems with the latest Windows 11 update and Rainlendar?

Problem solved. I did the install a few days later again to reproduce the bug. Everything worked. Rainlendar is running. Sorry. Windows…
