Update process doesn't exit properly?

I have observed this issue over the past few updates, basically, after a reboot, the nextcloud desktop client on windows notifies me that it will now perform an update. On confirmation, the client exits and apparently is updated in the background and restarts. Even though everything apparently went fine, I’m left with two nextcloud.exe processes in my task list, one of which takes up 20% of my CPU power (making the fan spin, which is why i noticed). Rebooting fixes the issue, but still I think this should not be necessary.

Anybody else observed this issue or is just my installation corrupted somehow?
