Marking this crash as a Beta release blocker.

This is marked as Beta blocker for M-64 and would be good to have all the Beta blockers resolved before branch point. M-64 will be branched in few days.

Could someone from skia team,please have a look ASAP and help in further investigation.

Likely related to the introduction of PaintFilter in https://chromium.googlesource.com/chromium/src/+/7865b5be0f6472b14ed7a30bc7e41896a8ec9e6e ?
Most likely a dupe of 788180.
