Blackscreen after login in

Hey, I'm having a big weird issue right now.
After login in normally, the screen turns black while flashing my only desktop icon for 3s, then it stops flashing.
I can see the cursor moving but I do not get any interaction at all while right clicking on the black screen desktop.
Applications that launches on startup works (Discord & Thunderbird) and I can switch to them with ALT+TAB.
I'm completely stuck with the black screen and cannot open any new software or the terminal.
I have tried with ostree 0 & 1 and I got same behavior.
Yesterday, It was working fine and I did not do anything since.
Right now, I'm completely lost and have not idea what to do except reinstalling.
For info, I'm on a PC with AMD CPU and GPU.
If you have any idea what is happening, please tell me. Thank you.
