@smoke007
Have you tried to do the following:

Restart your PC.
Install any pending Windows updates.
Fully reinstall qBittorrent (this means uninstalling, then deleting the %LocalAppData%\qBittorrent and %AppData%\qBittorrent folders and all their contents and then installing qBittorrent).

If the above did not solve your problem, you need to provide more information, such as:

What were you doing before qBittorrent started acting like this?
Did this behavior start after updating qBittorrent?
What was the last version that worked as expected for you?
etc

Yes, restarted both affected computers.
Yes, installed pending Windows updates and rebooted on both computers.
No, did not fully reinstall qBittorrent.
qBittorrent was sitting idle, except monitoring ShowRSS feed.
No, I did not recently update qBittorrent.
Version: v4.0.3 (64-bit) has been rock solid since upgrading to it back when that version first came out.

qBittorrent started crashing on both computers during the same evening. After doing the above troubleshooting steps, my guess was that there was a new bug that I'd need to wait to get fixed. So I left the computers and came back to them the next day. qB started up on both and ran for a while, then would crash again. Each computer would run qB for different amounts of time and after crashing, I would just re-open the app over. After several tries, it would stay running again for a while. I wondered if there was a network attack going on. Both of these computers are VPN connected.

I left the computers again for another day. This time, when I came back, each seems to be working fine. I think qB has crashed every now and again on one of the computers, but not the other. I've made no additional changes or rebooted either computer over this time period. Odd.. I've never had qB crash before; it's always been rock solid.

I had also posted one of the qB app crash dumps in https://github.com/qbittorrent/qBittorrent/issues/8341 seeing that others were having the same issue I was around the same time, thinking maybe it was related.
