Sentry shows that it received the .pdb and has symbolication data:

Possible resolutions:
* If we cannot get .pdb files working, we'll have to rollback to .dbg by reverting #14799
* I have opened a support ticket with the Sentry team in case there is help that they can provide

Version: 19.0.163-alpha
Regression-from: #14799
