Windows Terminal version

1.17.11461.0

Windows build number

10.0.19045.3448

Other Software

No response

Steps to reproduce

The issue could not be deterministically reproduced, however, it seems do be related to RDP disconnect or connect. I generally notice it either when connecting over RDP, or when connecting back to the local console.

Expected Behavior

No response

Actual Behavior

Windows Terminal is completely unresponsive, and uses 100% of a single CPU core.

Inspection of the threads reveals that one thread of WT is stuck at WindowsTerminal.exe+0xf9d0.

Not sure if this bug relates to #14483, which might also be RDP related, but does not appear to be stuck in the same code.
