20.04 update Screen turns purple

[thijsduinmaijer]

Today I tried to update my Ubuntu 18.04 desktop to Ubuntu 20.04 desktop.
My system has always been working as it should until now.

I followed this tutorial and everything went just fine: https://ubuntu.com/blog/how-to-upgra...0-04-lts-today
The update itself went smooth.
I was really exited to boot into the new version. The login screen works normally and after I hit the login button, my screen turned purple as you can see in this image:screen.jpg
My screen isn't frozen, it is just stuck there while being purple. When I try to move my cursor around, I found something interesting.
If i click in the top-right corner, I get this little menu which is shown in this image:button.jpg
Although I get a power off button, it wont power off so I have to do it manually with the power button on my laptop.

I'm currently on windows since I have a dual boot.
I hope someone is able to help me solve this issue since I can't use my Ubuntu system anymore and I'm hoping it could be fixed without a fresh install.

laptop information:
System model: HP Pavilion Laptop 15-cs3xxx
System type: x64-based PC
Processor: Intel(R) Core(TM) i7-1065G7 CPU @ 1.30GHz, 1498 Mhz, 4 Core(s), 8 Logical Processor(s)

I have 1 SSD TB drive which I have divided:
Ubuntu drive partitions:

I would love to hear how I can fix this! Thank you for your time reading this.

Kind regards,
Thijs

p.s if you need more information to help me please ask!

I've fixed this. It had something to do with my videocard.
