FWIW the problem does not arise with release_12_2 checkout of the git repo.

I did "git log --grep 'compilation-in-progress'" and with --oneline option the 
output is

be71fb7e Delete bogus defvar
087b0300 Simplify mode line for emacs 27
e78a13c0 * tex-buf.el: Address some compiler warnings

I could eliminate the first as culprit by installing fomr its parent.

The the second, I could not as "make" would complain, but I found the last 
release before it and it is release_12_2.

I installed it and no problem.

So perhaps look at 087b0300 whose commit message says

Simplify mode line for emacs 27
    
    * tex-buf.el: Don't add an entry in `minor-mode-alist' for
    `compilation-in-progress'. In emacs 27, compile.el adds a similar
    entry in `mode-line-modes'.
