Sorry this wasn't clear, I use straight to install packages which uses a
git repository to mirror eglot changes from ELPA devel:
https://github.com/emacs-straight/eglot.
Since this may not be familiar to you, I just took the
commit with the same eglot changes in the emacs repository.

The version of eglot I'm using is 1.18.0.20250302.222215 (from ELPA
devel: https://elpa.gnu.org/devel/eglot.html)

I haven't been able to reproduce the error so far.
As expected it will be difficult to fix the error without a repro. I
shared the stack trace in case it might be familiar to you. I guess we can
close the issue.

Thank you!
