Issue Description:

I'd love to play around with SE-0298, but all recent nightly builds are crashing for me with every non-trivial of my projects. Here is a traceback:

Assertion failed: (isActuallyCanonicalOrNull() && "Forming a CanType out of a non-canonical type!"), function CanType, file /Users/buildnode/jenkins/workspace/swift-PR-toolchain-osx/branch-main/swift/include/swift/AST/Type.h, line 402.
Please submit a bug report (https://swift.org/contributing/#reporting-bugs) and include the project and the crash backtrace.

As far as I can see the crash does not report the offending source line (only `Session.swift`) which is too big for me to triage and find the actual culprit. Is there anything I could do to help?

If you can share your project privately, you can submit a feedback report through feedbackassistant.apple.com and attach the project which would help. If that's not an option, you can narrow things down by bisecting (commenting out leaf functions or replacing implementations with fatalError("...") for non-leaf functions).
