Bug: Removing tab in full screen mode crashes app

[phougt]

Description

Greeting everyone,
Files crash whenever I close tab after creating it in fullscreen mode.
If I create a new tab in non-fullscreen mode, then delete it fullscreen mode, it doesn't crash.

Steps To Reproduce

1. Open Files in fullscreen mode (F11)
2. Add new tab.
3. Close the newly created tab

Requirements

I expected it to not crash after closing tab.

Files Version

3.1.1.0

Windows Version

10.0.22635.2921

Log File

debug.log

I can reproduce this issue as well. But oddly enough, it doesn't reproduce when I enable debugging in Visual Studio.

Thank you for the report

It appears to be caused by PR #14342 .

This issue seems to no longer occur in version 3.5.0.0. But keep creating and closing new tabs in full-screen mode (create ~10 tabs, close them all, repeat) can sometimes cause crashes.
