First try using Target API 3̶1̶/3̶2̶/33 and then later see if you need to downgrade any androidx libs which are using IStar attribute (which needs in api 3̶1̶/3̶2̶/33)

Update:
Those who don't get the issue fixed even after setting API 3̶1̶/3̶2̶/33, most likely you are on an older gradle version. For that would recommend to update your gradle version & android plugin gradle version. You can have a look here(check solution 1) on how to do that.

 

Some library was the issue, answer above solves it but I anyway have gone to Target 31. Waiting for crashes and bugs now.

 

It fixed my problem, thanks!!!

 

worked for me, thanks
