PS.: I put that it affects 1.15.2 because its the only version which I could select, I don't know why I couldn't put any other versions because it said they didn't exist!
I have two laptops and one PC at home. My PC works just fine and runs all versions, but for some weird reason, neither of my laptops can run any version below 1.12. Basically what happens is - when I select a version below 1.12 and click launch, right when the game is about to start, it crashes immediately "An unexpected error occurred and the game has crashed". I ran it with the game output and this is what i get: right after "Setting user" and "Session ID" I get 29 warns:

Then it says "LWJGL Version: 2.9.4" and "Inconsistency detected by ld.so: dl-lookup.c: 111: check_match: Assertion `version->filename == NULL || ! _dl_name_match_p (version->filename, map)' failed!
" followed by "Process crashed with exit code 127" fatal error.
For some weird reason no crash report is created.
