renpy 8.4.1 launcher lint isn't working

[standab32]

Over this past week, I tried to run the lint on my projects, even ones that seemed to run normally. But instead of the usual empty report, the launcher would freeze, then abruptly halt, leaving me with an unclear report of "ValueError: invalid mode 'w+'", implying that only modes such as 'r' and 'w' were acceptable. This only compounded my frustration since I don't operate in any folder outside of my game files.

I even tried the lint on the baseline projects, Tutorial and The Question. It just dumped this in response:

While running game code:

I would appreciate a solution, or at the very least some direction into fixing this matter. Some of my projects are vastly complex, with up to hundreds of variables and flags, and lint has been my go-to for managing them all.
