[Paint.net crashes upon opening]

Still gives the same error after restarting.

 

[Paint.net crashes upon opening]

Ran PdnRepair.exe, gave this output: 

 

The return code from this utility is 0 (success), 1 (fail), or an MSI error code like ERROR_SUCCESS_REBOOT_REQUIRED (3010).
Use /nopause to avoid 'Press Enter to exit...' at completion.

* Opening registry key, HKEY_LOCAL_MACHINE\SOFTWARE\paint.net: ok
* Retrieving MSI product code GUID from ProductCode value: {6FED3D93-C0FA-4BD7-A36F-7FC53698244F}
* Attempting to repair with MsiReinstallProductW(REINSTALLMODE_FILEREPLACE) (same as msiexec.exe /fa): success, but REBOOT IS REQUIRED, dwResult=3010

Return code is 3010
Press Enter to exit...

I'm restarting my computer now.

.NET Framework 4.8 is already installed on my computer. Paint.net still gives the same error.

Ran the SFC utility. Got a DISM log (File size too large for this site,) and the SFC scan prompted me to reboot after the verification step. After restarting, opening Paint.net gave me a new error message, similar to the first one.

Error message appears upon opening. I tried reinstalling the program (multiple times,) and running PdnRepair.
