Like the subject states. After starting Lightroom, it flat out crashes after 30 seconds or so.
Have tried SHFT-ALT combo to reset prefs. Also tried un- and re-install.

nothing helped. please advicee

Asking for clarification: when LrC crashes, do you have to re-start your computer (or does it restart automatically)?

No I don't have to restart. Lightroom just quits, disappears into nothing.

[UPDATE] I ended up opening a chat with a very helpful Adobe support person. They, at one point took over my PC and tried a couple of things. Although I'm still not sure what the actual issue was, he did the cleanest of re-install (meaning he ran Adobe cleaning tool to clean Lightroom and Camera RAW first) and now it works.

for future reference; this was all tried to no avail
- reset preferences by holding SHFT-ALT while booting Lightroom
- use clean / new catalog
- roll back to v9.4
- disable GPU acceleration
- disable all plugins

So, credit where it's due; Adobe's support person helped me for 3 hours and fixed it!
