Hey @HZ-Almaril
if you tried EA_Blueberry's steps can you try these steps?
I see a lot of Apphang codes, You may want to use the windows file checker.
Just to make sure all windows files are fine and maybe restore some corrupted files.
Press your Windows key, type CMD.
Then right-click the command prompt icon and run as administrator.
Now type here: DISM /Online /Cleanup-image /Restorehealth
This can could take a couple of minutes to start and maybe around 30 minutes to complete.
When that is done, try to run the sfc /scannow.
When you see Verification 100% complete, type exit.
Now open or download CCleaner.
Locate yourself to the Registry tab and scan for issues.
Click on Fix selected issues, it will prompt you to save your registry, just save this on your desktop just in case.
Then confirm again and let CCleaner do its job. when this is finished do a reboot and try streaming apex again.
Let me know if that changes anything.
