Writer on Windows 10 constantly freezing

Since yesterday Writer freezes up completely within a few seconds, or if I’m lucky minutes, on both DOC and ODT. I can’t detect any pattern to this behaviour. Once it happens I have to kill the process, then restore the file. I’ve tried entering Safe Mode and disabling hardware acceleration, and also deleting the user profile, but this has no effect.

I’ve got a new and pretty clean system, with no recent software installations except Microsoft updates, namely the May ‘Feature Update’ 2004, and the 2020-05 .Net framework one. I’m a bit suspicious about 2004, but whatever the cause, does anyone have any ideas.

Installed (64-bit) couple weeks ago and was working fine until now. This has been happening for the last 2 days for me in writer. Have 12GB RAM free. Have noticed a couple of unusual things though

roughly 1GB for opening LibreOffice to the main recent documents panel.

-100 or so MB for a new document

-3GB for the document I was working on.

-soffice.bin was hogging first cpu available to it (in excess of 70% whilst other cpus were at 5%).
Tried changing CPU affinity to test theory that LO wanted to hog the first processor available to it. Changed to processor #x and x was always hogged.

-a commit of 4.3GB

After closing off all LO processes for the night the crashing went away for a couple of hours but came back again, even after closing off all LO processes continually trying again, could only go a couple of minutes before crashing again.

Version: (x64), Windows.

I’ve got the same problem with version (x64) on my desktop computer.

It only started happening after I took the proffered Windows 10 2004 feature update.

The symptoms are that LibreOffice may work for a very short time but will freeze up very quickly whenever I use the scroll wheel or right mouse button. When scrolling down a spreadsheet the row number at the right hand side goes blank. When using the right mouse key for options it also goes blank. It would appear that the save button still works, though by that time LibreOffice is unresponsive.

I found that I can avoid the freeze situation by only using the left hand mouse button and the up, down, left and right cursor keys to navigate in Writer or Calc.

I definitely won’t update my Laptop to Windows 10 2004 given the current problem.

Anyone got any clues what’s going on

may or may not be related to post titled editing, adding, deleting of some text sequences in documents crashing LO writer

I have what seems to be the same problem. After a time that seems to be random, LibreOffice can’t display anything (but I manage to do some operations blindly with only keyboard). I encountered the problem in Writer, in Calc, in Impress and even sometimes in the starting page.
I had the problem with LibreOffice 6.4.4 64bit, so I uninstalled it and tried again with 6.3.6 64bit… same problem again.
My system is a fresh Windows 10 pro on a new computer, i7, 16GB mem.

In my case, the problem appears (mostly) when I use the mouse wheel (but not always).

Just a quick update.
I uninstalled the 64 bit version of on my desktop and installed the 32 bit version and the problem remained but occurred less frequently.
I removed my wired usb mouse and tried a wireless mouse. The problem went away.
I’ve now installed the latest 64bit version, still with a wireless mouse and no problems.
I’m baffled but the problem has now gone.
(For information I also upgraded my laptop to windows 10 2004 and have had no problems with the 64 bit version and a wireless mouse).
Whilst I’m happy the problem has gone, I wish I knew why.
