File not found message, but everything is ok

I usually login to my nextcloud AIO 8.0 (nextcloud 28 latest stable) in one tab, then clone them inte a 3-4 more. Later on when using one of the tabs moving up or down a directory I get a message “File not found” but everything is ok. I can get rid of it by doing a refresh on the whole tab. It is however a bit irritating/frustrating having to close these messages for nothing. What (temporary?) file is it complaining about, and is there a way to get rid of this message?

Hello. I have the same problem. Did you manage to solve it?
