Support for macOS Monterey was added with the 2022.2 Preview 1 release, but the M1 chip is still not supported hardware, which is likely causing the issue. Support for the M1 chip is expected later this year or early next year, but until then some issue may still occur.
Some troubleshooting steps that may help are to follow the steps in the Twinmotion is not visible after splash screen article, which can reset Twinmotion's configuration and resolve some issues.
I had done the verification from the Epic Launcher, did not work.
But erasing the Config folder did it. I really like 2022.2.P1
Great !
Thanks also for the insight on the M1 support. Twinmotion is already quite fine on Rosetta. But it will be a blast once native. It will put quite a challenge on other rendering softwares, I think.
