Zwift crashes on me after about 2 hours

I usually ride about 3-4 hours. Recently zwift crashes after about 2 hours. the longest has been 2,5h then it went down.
I think it is zwift that is playing up, because sometimes the screen freezes and I can terminate the zwift process and restart it. Most of the time it also takes down Windows and I have to restat the PC.
Anyone have an idea what I can look into that could solve this issue?
I think it started with version? 1.78 but could have been the previous version.

I reinstalled Windows. reinstalled graphics drivers. Played around with BT, ANT+ or Wlan connection to the wahoo. Reinstalled zwift.

It worked without any flaws the past 4 years.
What changed is that I had a Stages SB20 and now a wahoo kickr. It worked without a problem at first. Can that thing have a pronlem that causes Zwift to go down? When all is running there are no issues whatsoever, just after about 2hours the screen freezesā€¦
