I just got report that the msi was the new version 3.5.9.0 for someone else
please retry (in case still same issue: you could deinstall 3.5.8.9 or which version you have and install the new msi)
It's also a good opportunity now to make a !backup
The terms above starting with ! are commands which the fediverse-bot accepts and provides further info on
(see point I. here )
My bad! Deinstalled the old version and now everything works!
Sorry for the circumstances.
