Same issue on my system. Every few days my template freezes while trying to open. It is completely inconsistent and happens at different stages.

Best of luck!

VEPro 7 latest version, on the new Mac Pro 16-core 160 RAM, macOS Big Sur.

The same thing is happening for me in VEPRO 7. Constant crashes if I accidentally hit the up or down arrow. I did not experience this problem in VEPRO 5.
