I suspect that this is the same root issue as #2188 -- can you try :VimtexCacheClear kpsewhich with the latest VimTeX commit?

@clason the error goes away. However the available command is :VimtexClearCache.

Oops, sorry! Should have copy&pasted the whole command ;)

I'll update the error handling so it also captures this error.
