Has anyone else had MAMP Free stop working unexpectedly on an Apple Silicon Mac? Whenever I launch it, I get the error "PHP versions failed to initialize." I initially wondered whether this was a widespread issue related to PHP 7.4, but I meant MAMP version 7.4—the configured PHP version is actually 8.3. Clearing system caches and preferences hasn't helped. It also seems like MAMP Pro may still be working, so this could be a bug specific to the free edition.

Make sure the versions aren’t being mixed up: MAMP 7.4 is the application version, while PHP 8.3 is the runtime version. Checking the MAMP logs could reveal the exact initialization failure, but based on the reports so far, this appears more likely to be a bug in MAMP Free than an issue with PHP 7.4 itself.
I’m seeing the same failure and it started recently. Clearing the system cache and MAMP preferences didn’t make any difference, so it may be a broader problem with the free version rather than a local configuration issue.

That matches what I’m seeing. It looks like MAMP Pro continues to work, while MAMP Free is the one failing.
