Is this a new bug in dbt v2.x compared to the latest version of dbt 1.x?

I believe this is a new bug in dbt v2.x
I have searched the existing issues and could not find a duplicate

Current Behavior

I'm on versions:

dbt-core==1.12.3
dbt-databricks==1.12.5

I tried the v2 parser and now I get this failure "Could not load fusion-produced manifest"

That temp folder mentioned in the error is gone as soon as the command is complete so how do I figure out which model this error is related to?

Expected Behavior

It shouldn't fail.

Steps To Reproduce

Run a dbt parse and I get:

10:53:30  Running with dbt=1.12.3
10:53:50  Delegating parse to v2 parser: dbt-core-experimental-parser parse
  dbt-core 2.0.0-rc.1
   Loading profiles.yml
  Finished [  0.18s] resolving packages from packages.yml (4 items)

=================================================== Execution Summary ===================================================

10:54:04  v2 parser failed after 14.11s (FusionParserSchemaError, exit_code=-1)
