Spontaneous Access Violation errors when remote is set to false

[PerplexedFox]

I described the error in the following stackoverflow question. The interesting part is that as soon as I returned to the previously working code (with constant pressure and other variables determined from coolprop with bsplines) suddenly the error appeared and would not go away.

Error: Exception: Access Violation
At line 3157 of file custom.f90
Traceback: not available, compile with -ftrace=frame or -ftrace=full

Error: 'results.json' not found. Check above for additional error details

FileNotFoundError: [Errno 2] No such file or directory: '...\options.json'

If solved with Remote=True the error does not appear at all!
Update: since today the remote solution results in

HTTPError: HTTP Error 404: Not Found
During handling of the above exception, another exception occurred:
ImportError: No solution or server unreachable.
Show errors with m.solve(disp=True).
Try local solve with m=GEKKO(remote=False).

It does seem like the issue 2 years ago, where the solver crashed...
