Thanks for the reproducer code.  I've bisected this back to b2b023c657ba8c3f4a24d0c847d10fe8e2a73d44 which fixes other known bugs in the lru_cache in issue 35780.  The problem is due to the lines that use a scalar instead of an args tuple for exact ints and strs.  I'll work-up a PR to fix it soon (I'm on vacation and have limited connectivity so it may take a few days).
