It was very hard to debug it, I thought that it's local dev server problem but I catch it at last
1. Win 10 Pro LTSC
2. PhpStorm 2023.1
Local server works, non php project opened and no problem at all The problem starts when I swich to Magento 2 project, not depend of PHP version, 7.2, 7.4, the same. php + cmd processes multiplying like the virus. Sometimes I can catch this moment and use “taskkill /f /t /im php.exe”, sometimes not and 90+ of RAM used and terrible freezes.
Generally everything can work ok and then suddenly starts. 3 times killed processes, reload Storm and 15 minutes everything is Ok now but temporary anyway.
UPD, was finishing the message switched to non php project and back. Multiplying started again, taskkill /f /t /im php.exe, looks like quiet now
