The answer in this scenario is to exempt that application and/or folder. Don’t throw the baby out with the bath water.

In my environment we have to add exceptions for Developers git folders for the realtime scanning for a similar reason. Apps with large numbers of small files or high frequency writes of smalls files, like temp files during the build process, need to be exempted unless you’re willing to pay the performance penalty for the security.

I don’t understand why, but I have an exemption for that folder and I’ve disabled real time scanning. It still shows the slowdown on first launch. The only thing that works is disabling windows defender entirely. I’ve been through the troubleshooting loop a few times with this.

Out of curiosity, does Dev Drive do anything for you? https://learn.microsoft.com/en-us/windows/dev-drive/

I'm setting one up tomorrow.
