PUN throws errors in clean build. The question was asked in October 2020. No one answered.

Hi!

In October 2020, I asked a question to which I still have not received any answer.

The error only appears in build. I can't set a break in debug.
https://forum.photonengine.com/discussion/17117/the-error-only-appears-in-build-i-cant-set-a-break-in-debug#latest

The question is still actual for me.

PUN stops working correctly and starts throwing errors in the build without the Development Build check mark.

If the Development Build checkbox is enabled, then everything is fine.

Errors:
