Import window opens at all time even if not required

Hi everybody,

I'm new in the community but I would like to ask for someone help.

Using Lightroom Classic (latest version 10 installed) every few seconds the import window opens even when not requested.
Both cancelling the operation or closing it, after a while it reopens. This is not allowing me to work any picture and makes LR useless.

Did anyone already experienced this problem? Any idea on where to check/change to avoid this?

It is going on since few weeks and I cannot find any solution so far.

Even using the Cleaner Tool, no way!

Thank you all in advance for any suggestion or help

Ciao

Giovanni
