Thank you, that helped.
I also noticed that it happens repeatedly after each machine restart, so I created this batch script, which needs to be executed as an administrator.
@echo off
setlocal enabledelayedexpansion
REM Define source and destination directories
set "source=%ProgramFiles%\DVDFab\StreamFab\CEF\WidevineCdm"
set "destination=%LocalAppData%\CEF\User Data\WidevineCdm"

echo Deleting existing WidevineCdm folder...
rd /s /q "%destination%"
if %errorlevel% neq 0 (
echo [ERROR] Failed to delete the WidevineCdm folder. Please check permissions.
) else (
echo Existing WidevineCdm folder deleted successfully.

) else (
echo No existing WidevineCdm folder found. Skipping deletion.

if not "!src_sha1!"=="!dst_sha1!" (

set "checksumOK=0"

set "checksumOK=0"
)
)
if "!checksumOK!"=="1" (
echo All files copied successfully with matching SHA1 checksums.
) else (
echo [ERROR] File verification failed. Please review the errors above.

This batch script: - Deletes the existing WidevineCdm folder from %LocalAppData%\CEF\User Data\.
- Copies the WidevineCdm folder from %ProgramFiles%\DVDFab\StreamFab\CEF\ to the same location.
- Verifies that files are copied correctly by comparing their SHA1 checksums between the source and destination.
- Displays errors if any step fails without immediately exiting.
- Prompts the user to press Enter to exit after completion.
It ensures both file integrity and error reporting during the process.

FYI, if it shouldnt work, you will need to change this line:
set "source=%ProgramFiles%\DVDFab\StreamFab\CEF\WidevineCdm"
to this
set "source=%ProgramFiles%\StreamFab\StreamFab\CEF\WidevineCdm"
