error in phy2 loading leads to a clean up in the "cluster_group" file

[allllex3202]

Hi Experts,

I saw this error when I try to open new sessions today:

QWindowsWindow::setGeometry: Unable to set geometry 4905x1000+40+57 (frame: 4921x1039+32+26) on QWidgetWindow/"TemplateGUIWindow" on "\.\DISPLAY1". Resulting geometry: 4355x1000+40+57 (frame: 4371x1039+32+26) margins: 8, 31, 8, 8 minimum size: 4355x115 MINMAXINFO maxSize=0,0 maxpos=0,0 mintrack=4371,154 maxtrack=0,0)
QMimeDatabase: Error loading internal MIME data
An error has been encountered at line 1 of : Premature end of document.:
22:48:18.773 [I] supervisor:702 Assigned 1873 spikes.

The session can still be loaded as usual, but when I hit the "save" button, the text in the "cluster_group" file will be cleaned up which is a disaster cause we can't read any neurons activity after that...

I've been using the same setting on the same PC for a while so a bit confused why this happens? And any suggestions about how to fix?
