Em Client 10.4.5 hangs after sleep

Good day, last week I updated to 10.4.5326.
I am on Win 11 25H2. EM Client is installed on the C-drive (SSD1). The data files (and backup-folder) are on the E-drive (SSD3). Usually I reboot about once per 1-2 weeks.

Since the new version: After every time I put my computer to sleep (basically, every night) EM client hangs. I cannot move the window, or interact after waking the computer.
When I rightclick the icon in the taskbar I can click on “new mail”. This will open a new Mail window, which is then also “stuck”.

Ending the application, and restarting, does not solve this. I have to reboot the computer to get EM Client going again.

Which logging could help in this case?
Is there anything obvious I can try?

Could possibly be your E drive is not waking up after sleep? A couple of suggestions:
Check Windows Update and apply any Optional updates
Try disabling FastStart (2) and Allow wake timers (3) in this post:
