Rails App crashes when https request is made after upgrading to macos Tahoe 2025

Maybe this can help you. It was an issue with Tahoe connection with PG. As you are doing an HTTPS connection it may be related.

Looks like the problem is just spring

Everything works, but not if spring is used

IMHO the best solution is disable and forget it

bin/spring stop
bin/spring binstub --remove --all
bundle remove spring

I also used this utility, but it does less good than harm

Running for hours after heisenbugs is not the most pleasant activity

I can see your puma version 6.4.3 which had some issue with openssl version determine logic, if you upgrade to 6.5 might solve your problem, because they fixed some openssl version determining issue.
You can check details from https://github.com/puma/puma/compare/v6.4.3...v6.5.0 here. ext/puma_http11/extconf.rb
