Failed to parse the configuration file at ... config.xml

Hello,

From time to time Synctrayzor (1.1.21) fails to start. This happens on two different Windows 10 laptops, maybe every month or two. A dialog box appears with the message:

Failed to parse the configuration file at C:\Users\Márcio\AppData\Roaming\SyncTrayzor\config.xml '.', hexadecimal value 0x00 is an invalid character. Line 1, position 1. _(Translated from Portuguese)

Looking at config.xml I can see that all characters have been replaced, somehow, by the null character.

I don't care about going to %appdata% and deleting the file, but other people here have trouble with this. I have found a similar issue https://github.com/canton7/SyncTrayzor/issues/120 but it is closed.

Thank you for SyncTrayzor.

Greetings, Márcio Moreira
