Unable to create WinPE.iso

[admin]

Hi. I’m a newbie and with a Windows 10 22H2 PC, I made some backups with Hasleo v4.0.
Today I realized that, after upgrading to v4.0, WinPE.iso was not present in the Hasleo ‘bin’ folder.
I then launched the emergency disk creation procedure. After about 1 minute, the procedure stops at 63% and there it stays forever (the background Hasleo Backup Suite Service Application process is shown as "suspended"); I cannot close the application and the only way I can break the situation is to reboot the PC.
I tried several times with the same result.
Looking at the contents of disk C: I noticed that a “WinPETem” folder had been created with a new folder inside named 
55ce1990-2ca1-4c0e-af66-6c455aad8d84 with subfolders:
C:\WinPETem\55ce1990-2ca1-4c0e-af66-6c455aad8d84\
            ISO\boot
            ISO\efi
            ISO\source
            mount\Program Files
            mount\ProgramData
            mount\sources
            mount\Users
            mount\Windows
I also noticed that each time I tried to create the emergency disk, a subfolder similar to the one described had been created in C:\WinPETem folder which has reached 16 GB.
I am Administrator with full control over disc C: and I tried to delete C:\WinPETem. But the deletion is not allowed (access denied).
For info I have a second photocopy PC where the iso creation worked correctly and where no C:\WinPETem was created.
I tried to re-install v4.0 on itself (without uninstalling it first) without success.
I don't know what to do anymore and especially I don't know how to get rid of the C:\WinPETem folder which has reached 16 GB !...
Any advice?
Thank you very much

P.S. - I managed with difficulty to delete the C:\WinPETem folder by booting with Linux, but now I am afraid to run the emergency disk creation procedure again.

Open an elevated cmd.exe in Windows, and run the following command:
Dism /Unmount-Image /MountDir:C:\WinPETem\55ce1990-2ca1-4c0e-af66-6c455aad8d84\mount /discard
After that you should be able to delete C:\WinPETem normally.

Regarding the issue of getting stuck while creating WinPE, this is rare and we recommend that you wait a little longer to see if the operation can be completed. And please try adding Hasleo Backup Suite (BackupMainUI.exe, BackupService.exe, BackupWorker.exe and BackupSystemTray.exe) to the list of allowed applications (may be called Trusted Applications/Whitelisted applications) of your anti-virus software to see if the problem still persists?
