Has anyone else run into this today? I'm using the free edition of MAMP on an Apple Silicon Mac, and every launch now shows the error "PHP versions failed to initialize." I initially wondered whether it was related to PHP 7.4, but my configured PHP version is actually 8.3. Clearing system caches and preferences didn't help. It seems the issue may affect the free edition specifically, while the Pro edition is still working.

I’m seeing the same failure and it started recently. Clearing the system cache and MAMP preferences didn’t resolve it, so this looks more like a current bug than a local configuration problem.
Double-check the version details before assuming PHP 7.4 is the cause. The problem appears to be with the free edition of MAMP itself; PHP 8.3 is configured, and the Pro edition reportedly continues to work normally. Checking the MAMP logs may still reveal more details, but this could require an application update or vendor fix.

That matches what I’m seeing too. Clearing caches had no effect on my installation.
