Xcode 12.3: Failed to re-create a coordinator for com.me.myapp

I’m getting the following message while trying to launch simulator

System Information

macOS Version 10.15.5 (Build 19F101)
Xcode 12.3 (17715) (Build 12C33)
Timestamp: 2021-01-25T15:50:20+01:00

I also found that it works Ok if i launch it on another device simulator (lets say iphone 11 pro instead of 12 pro) but i’d like to fix this somehow.

What i had already tried:

• cmd+shift+K
• rebooting mac
• quitting xcode

Xcode: Version 12.3 (12C33)

any ideas on how to get it fixed would be appreciated
