n/a

Steps to reproduce

When I have many tabs open (sometimes multiple windows in one tab) and I close them (usually ctrl+d I am in linux subsystem), there is this closing animation where tab disappears and during this Windows Terminal is randomly crashing. It only happens like in 1 out of 10 close operations, not always.

It's only happening when closing tabs (or parts of tabs) and it's really annoying. I stopped closing tabs for this reason only, which leads to massive clutter.

When it crashes it doesn't say anything, just whole app closes with all its tabs.

Expected Behavior

Not crash when closing tabs, or at least show some error message that helps to debug the problem

Actual Behavior

The program is crashing when I am closing tabs
