I downloaded Maya2020 trial (for business user + single user) to my macbook pro(16-inch, 2019, macOS Big Sur ver 11.1). It worked well at that time and I shut down the macbook as normal. However, when I used the macbook today and launched the Maya app again, it popped out stack trace error message. I have found a similar issue here but its solution was about versioning.
I have re-installed a few times but it didn't work. I have also reset the maya preference as mentioned and still not working. Here below is the error message and hope that someone could help:
