Probably all of the above. Please read this short essay…
It was most likely something the original poster did. The most likely culprit would be some foreign package. As @philm said…
But we don’t know what the OP did to create the problem they were having, because quite obviously, they abandoned this thread 24 days ago.
For that matter, please do not necro-bump old threads. If you have a problem — and especially so if you are not the original poster of the thread you are reviving — then simply start a new thread.
The rule here is one issue per thread and no thread hijacking.
That said, I wish you a pleasant stay here at the forum, but given that the OP has bolted, I am closing the thread.
