Hello @z00z thank you for the update and sorry we missed your post.
To better help you with this issue, we will need to gather your msinfo and dxdiag files as the troubleshooting we have given you, has not helped you so far.
Your system files should shed a bit of light on other possible causes and give us the install locations, as well as any Windows and program faults that could be causing this.
You can find instructions on how to create the system files we need, below >
DXDIAG - https://ubi.li/msrxL
MSINFO - https://ubi.li/lmiCE
Please upload your system files to this case, using our Ubisoft Support website here and leave a brief explanation of the issue, as well as what you have tried so far, to save time > https://www.ubisoft.com/en-gb/help/cases
Once we have received these files, an agent should get back to you within 48 hours.
