Archicad 27 freezing at random moments on PC. Anyone else?

[Paul Chebiniak]

HELP!
I have been recently experiencing serious freezes at random times using Archicad 27 on my Windows pro 24 PC.

Its been happening for a couple of weeks now. 

I will get the blue processing circle in place of the cursor, and it spins for maybe 20-30 seconds. I do not crash. God forbid I click the mouse a few times because when ArchiCAD wakes back up, every click that hit an object, will have altered the model. Thanks for all the "undos" allowed. LOL

There is no specific trigger. It even happens even while I'm not doing anything. 

I switch between a Mac intel at the office and a windows PC at home. Does not happen on the Mac. 

It does not happen with other software on my PC. 

It does not matter if I have chrome or my Foxit PDF editor, or any other software open or not. 

I have never experienced this before and wow its very aggravating and a major interruption to my workflow.

My project size is small, about 100kb, and the task manager does not report big up-tics in processing when happening. 

Any help is appreciated!

Operating system used: Windows 24H2

Update.

in the spirit of trying any and everything...

I tried removing and re-installing archicad, and the problem remains.
