Steps to reproduce
#81861.blend

Open file
Switch to rendered mode

Grab vertices move them in circular trajectory with as big radius as you can

if you move the viewport camera the crash may not happen. Provided setup seem to crash for me in every case though.

Seems Embree related, can you confirm this also crashes in 2.90 / 2.90.1 but does not crash in 2.83? (you can get the releases here https://download.blender.org/release/)

Checked:

2.90: Yes, this indeed crashes in 2.90, almost immediately, crashlog attached
CrashOnEditingCurves.crash.txt
2.83.7: Yes, this indeed DOES NOT crash, tried for a minute.
// But proportinal editing works only on active curve in multiedit mode (in 2.90 it works on both objects and all points - as it should according to tool settings)

Yes, this is new in 2.9x, see a64b8aca39

Can confirm, but it may be tricky to reproduce. I will upload file hopefully in a state, that will crash for 100%
