Finder launch and quit after booting

I've started noticing that, after booting and launching all app that was on at the time of shut down, finder simply quit after ~10 sec and I have to turn it on manually. I didn't recall this issue before Mojave (but maybe it was already like that, I barely turn off my laptop - just closing it).

It doesn't seems to crash as there is no warning like "finder quit unexpectedly" or anything...

When opening console after finder quit, this output appear :

[ApplicationManager statusChangedForApplication:] | In status changed, finder quit, calling to get number of foreground apps

Disk utility check says everything's fine, and I just did a clean install as my MBP crashed during last update.

What could be the cause of Finder quitting after launching all app ?

MacBook Pro (13-inch, 2017) version 10.14.4 (18E226)

EDIT :

I find out that when I open pCloud, Finder quit (but still not crash)

Console output :

[GUIApplicationLogout loadProccessesToQuitArray] | Checking app: pCloudFinderExt

Solution 1:

Have you tried logging out & unticking the "Reopen windows when logging back in" option?

Else you may have corrupted user Caches/Saved Application States.. you could try removing the content of these folders & rebooting:

~/Library/Caches

~/Library/Saved Application States

After emailing pCloud support, I got this answer :

Yes, this is a behavior that was desired - launching the virtual disk restarts Finder to support it. But we noticed that sometimes he does not want to restart depending on the machine and the OS. These are isolated cases, but we decided to launch the next update without this behavior. I hope very soon we will have it available.

So I´m guessing I just have to wait for the next update...

Meanwhile, I unchecked launch pCloud when starting the system inside pCloud app and disable it to the Login Items pane of System Preferences and no more issue !

EDIT : pCloud 3.8 seems to work just fine on Mojave 10.14.6
