Nextcloud 3.0.3 desktop client getting flaky

Recently, I have taken to checking my Nextcloud 3.0.3 client at the start of each day, to make sure it is still running.
Then, almost without fail, at some point in the day, it will stop working and need to be manually initiated.
I don’t understand the issue, why is the Client stopping without a warning, message, or error?
THX,
