OBS webcam issues

Hey guys,
I have a problem with the webcams in OBS, and I really don't understand anymore.As a little introduction, I have been working in the IT for over 7 years now. 2 years software and 5 years hardware, so you can assume my knowledge exceeds above average.
This is the problem:
I have 2 pc's
Whenever I connect 3 webcams through OBS on pc 1, it will only work with 2 webcams.Whenever I connect 3 webcams on pc 2, it will work with 3 webcamsThe webcams I own are:
  • Logitech C910
  • Logitech C270
  • Microsoft LifeCam Cinema
Whenever I try this without webcam drivers, only the Microsoft webcam works. Whenever I install the drivers for the Logitech webcams, only those 2 work and the Microsoft one fails.The webcams do get recognised by Windows, and they all work in any other app, on their own.
the 2 pc's are different concerning hardware.
PC 1:
  • CPU: AMD Ryzen 5 2600x
  • RAM: 16gb ddr4 3200mhz dual-channel
  • GPU: GTX 550 TI
  • Motherboard: ASRock B450m Pro4
  • OS: Windows 10, 2H20 update
PC 2:
  • CPU: Intel Core i5 (Some older model, 3rd gen)
  • RAM: 4gb ddr3 1333mhz dual-channel
  • GPU: MSI gt610 v2
  • Motherboard: An Asus (Don't have the exact model at hand at the moment)
  • OS: Windows 10, 2H20 update
I have been searching and troubleshooting for days now, I seem to find multiple people that have a somewhat similair problem but have no fix.I am almost certain this is an OBS specific issue, but I question it because it works on pc 2 and not on pc 1

Things I have tried:
  • Use both 32 and 64 bit version of OBS
  • Update to the lates version of OBS
  • Run OBS without webcam drivers
  • Run OBS with webcam drivers
  • Use the webcam drivers that come with Windows
  • Use the webcam drivers from the manufacturer
  • Run without any drivers
  • Try with a different webcam than the Microsoft one
  • Check the OBS logs for any weird data, none found
After al these tries, OBS still refuses to show me the footage of the third webcam.
It sometimes shows me the footage of the third webcam, but OBS then crashes.

PLEASE, help me out.
