[Bug] matomo just upgraded from 5.1.1 to 5.1.2 : console ok, web error 500

[franck-paul]

What happened?

Cannot use the web interface, only console is working

What should happen?

Should have web interface running, only got:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator at [email protected] to inform them of the time this error occurred, and the actions you performed just before this error.

How can this be reproduced?

Had Matomo 5.1.1 installed on local machine, PHP 8.3, MySQL 5.7, Apache 2.4, everything running.
Update directly from web interface and got error 500
Nothing in Apache/PHP logs

Note that all console command run fine (core:update, core:purge-old-archive-data, …)

[franck-paul]

It seems that the line 34 in file core/Intl/Locale.php : setlocale(LC_CTYPE, ''); causes the error on MacOS.

@franck-paul Thank you for creating the issue and bringing this to our attention. We are trying to replicate the error and can we ask if you are still experiencing the issue?

If yes, did you encounter the error 500 after clicking this button on the Dashboard?

This is most likely a duplicate of #21126. The issue wouldn't relate to the upgrade of Matomo, it's likely something else changed at the same time within the OS itself, such as a version upgrade of Apache or PHP etc.
I don't think we have a solution to this for MacOS.
@franck-paul are you by chance running Laravel Valet as your webserver setup?
