This is a known issue introduced by the fix to this issue:
    https://github.com/latex3/latex2e/issues/414
and it's already reported here:
    https://github.com/latex3/latex2e/issues/421
    https://github.com/latex3/latex2e/issues/422

This currently happens when you load a class file with a path, like:
    \documentclass{path/to/myclass}
then xkeyval complains and options are not correctly passed.  Meanwhile
you can either move your class file to the same folder as your main .tex
file, or use:
    \makeatletter
    \def\input at path{{path/to/}}
    \makeatother
    \documentclass{myclass}
which should work (even though it's not officially supported syntax).

I hope to have this fixed in the next few days.

Sorry about the trouble.

Best,
Phelype
