QCAD Professional Trial Version 3.32.2.0 (3.32.2)
M1-Max-Mac Sequoia 15.4.

Using the Library Browser somehow corrupts the QCAD config file.
Closing and restarting the application fails.

QCAD start up as new when deleting the config file or with only removing the entry:

[Appearance] DockappWindows="@ByteArray(…)"

The corrupted line seems to be much shorter: 6k vs 17k characters in my case.

The user can replicate the issue just by opening the Library Browser dialog.
Using 3.32.2.0 trial on Win7 32bit installation by ZIP I cannot reproduce the failure.
