After upgrading from Vivado 2020.1 to 2020.3 the clock wizard causes problems. Vivado crashed repeatedly when I tried to open the old clock generator. I had to delete the old clock generator and create a new one, using the clock wizard. Then I get the following problems:

The device XC7A100T is not listed as an option in Vivado version 2020.3. It only has XCVC and SCVM devices. It has changed my XC7A100T to XCVC1802. This explains the error messages. But why are the 7 series devices not listed in version 2020.3, and why has it changed my device to something else?
I can still open version 2020.1 and see that XC7A100T is still listed among supported devices, but version 2020.1 will not run after I installed version 2020.3. Both versions are installed on the same computer.

Refering to the download page, Vivado 2020.3 is recommended only for Versal devices. So, the problems can be this odd version itself (even labeled 2020, but released 2021..- the art of versioning). I think you should keep 2020.1, go to 2020.2 or wait for another version.

Thank you Micha
I would expect a more straightforward error message rather than just changing my device to some other device that causes tons of error messages and lots of headache.
