Unexpected Error: Please help decode

I am getting unexpected errors every time I try to run my app, would appreciate any help in understanding. Here are the last two I got:
anvil.server.ExecutionTerminatedError: Server code exited unexpectedly: a4a60d7414

anvil.server.ExecutionTerminatedError: Server code exited unexpectedly: e594f4b434

This probably isn’t your Server Code, but Anvil’s. The hex code is an event signature, so that they can find it in their logs, not something you’re expected to decode.

It’s probably already raised some flags at their end. But if it’s not addressed soon, you could always email support.
