We are trying to update a project on Unity 2020 with URP 10 to Unity 2022 URP 14. After updating it says the URP has been updated and needs to reload the materials. Then it starts importing with the green progress bar. It gets nearly to the end and says finishing up and then it just hangs and never advances. Sometimes Unity will just crash, no error message or anything. When I open Unity again it just brings up the need to update URP message again. and I start all over again with the same results. I can’t do anything else in the editor until this completes, I can’t even stop it from coming up or cancel it.
I highly recommend that you update one major version at a time. Try updating to 2021 first and running the material update process and then do 2022 and see what the results are.
