When trying to change an customers sizes she gets this error

Hello Everyone,

For an user of umbraco I have an question.
Yesterday she got this error code, i’ve already tried different things.
I sum up some of the things i tried.

(I am new to Umbraco, I cannot get into the back end to change settings in there, I just started working on this since I got an new job with another company)

Some solutions i tried,

also tried reinstalling frameworks but this didnt do nothing.

Tried to delete all cookies, all files in the %temp% files too,

Re-register jdscript.dll and vbscript.dll. If you still see error 0x80004005 after trying to unzip files with other extraction tools, then re-registering these two dynamic link libraries (DLLs) may help.

Delete temporary files. In some cases, a corrupt temporary file can cause error 0x80004005. Use the Windows Disk Cleanup tool or type %temp% in the Windows search bar to find the Temp folder and delete everything inside it.

Add a key to the Windows Registry. If you suspect error 0x80004005 in conjunction with copying or moving files, open the Windows Registry Editor and go to HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System.

We tried to clear cache, clear %temp%, clear Temporary ASP.net files.
Tried reinstalling all dot.net programs,
Installed newer .net (beta) even installed the newest SDK programs, but nothing seemed to work.
Then we tried running and changing customer sizes through mozilla firefox, this worked but the problem with Chrome and Edge still persist.

On a 32-bit system, create a new DWORD registry value called LocalAccountTokenFilterPolicy.
On a 64-bit system, create a QWORD registry value called LocalAccountTokenFilterPolicy.
In both cases, set the value to numeric 1 (on), then select OK. After that, restart the Windows PC to see if the problem is fixed.

The problem underneath
