XD freezing crashing on shared coedited canvas (Lenovo ThinkPad E14 Gen 2 AMD Ryzen 7 4700U Radeon)

Hello

ISSUE

Week 49 we had a shared project. 6 people in the same country on a shared canvas.

I had extreme crashes, freezing. Especially when editing text. Particularly 2nd, 3rd December.

Adobe may have gotten dozens of crash reports from me.

Wednesday Thursday (2nd, 3rd) I was basically restarting freezing restarting all day.

Had Microsoft Teams open other than XD everything else closed. 

Even moved Teams to mobile and had only XD open.

PC was even overheating!

Totally failed my group.

I came in with lame excuses on 'technical issues' which everyone was very nice about. 

(But secretly, people probably just think... yes, excuses, excuses, whatever.)

SYSTEM

XD works fine on my cloud. I have three internet connections (shared and private).

It's a new  PC bought in September used only for this course.  (LenovoThinkPad E14 Gen 2 AMD Ryzen 7 4700U with Radeon Graphics). Have submitted similar ticket to Lenovo.

I have Malware bytes, Hitman Pro. I regularly update Windows. On that day I restarted,  checked updates, scanned with antimalware. 

3rd Dec, Thursday evening there was an XD update, everything seemed ok after that.

However I am dreading the upcoming shared project and another fiasco debacle.

What could be the issue, and what can I do to avoid this in the future?

Thanks!
