Sure @mia !
Actually, I found out that this problem is related to the problem I reported earlier in this thread, and that is not yet solved.
Here is what I get If I start insync with --no-daemon:

As you can see there are several errors with the message Network service crashed, restarting service.
Every time this message appears on the console, I get a popup window in KDE saying that QtWebEngine crashed.
If you look closer at the log, you’ll also see this message right before every crash: /usr/lib/insync/libnssutil3.so: version `NSSUTIL_3.108' not found (required by /lib64/libsoftokn3.so).
Now if you look at my previous thread, you’ll notice that I was reporting problems with library libnss3.so, and that I had found a workaround by removing that library from the /usr/lib/insync directory and instead putting there a symlink to my system’s libnss3.so library.
So today I tried to remove the link and reinstate the original library, but if I do this, then insync does not start anymore, with the same error as reported in my earlier thread.
So the symlink is still the only way to have Insync working on openSUSE Tumbleweed, even though the recent Insync update added this instability in the networking code (and did NOT fix the original problem).
A final note: Insync is working despite the continuous crashing. When it is idle, there are no crashes at all. It’s only when it’s actively syncing that the crashes appear.
