At least 1 module failed remote validation

Summary

Since the v40.00 update, I get the following error whenever I try to launch a session and cannot start it:
“At least 1 module failed remote validation”
I have already tried the workarounds mentioned in previous forum threads:

Launching a session from a different account
Clearing the source file path cache via Help → Clear Source File Path Cache

Unfortunately, neither of these resolved the issue.
