Whenever I open XSplit gamecaster my game starts lagging immediately

Hi- I recently have had this problem with XSplit Gamecaster, that whenever I open up XSplit gamecaster, my game immediately starts lagging and stuttering. I also experience very low sensitivity in game(DOOM: Eternal) when Gamecaster is open. Any advice on how to fix this?

Gamecaster settings:
Ingest Server: Best Match
Resolution:1080p Full HD
Codec:Nvidia NVENC (uses dGPU)
Frame rate:60
Quality:Very High
Split recording:Disabled
Multi-track audio:Enabled

Intel Core i5-7400 CPU @ 3.00GHz
Nvidia GeForce GTX 1060 6GB

By low sensitivity you mean mouse sensitivity or something else? And as you mention, all issues occur just by having XSplit Gamecaster open, without even streaming or recording yes?

Yes, but I fixed the problem by disabling windows game bar and GeForce Experience in-game overlay.
