Same here. I have 30,30.
This is unrelated with the desktop issue. 
The env file is written pretty often.

If your backup is months old, then maybe some functions in the IDE

Restart lazarus making sure the config is working. 
Make a backup of environmentoptions.xml.
When the next time it happens, send the backup and the current
version.
