Error with opening project Davinci Resolve MAC OS

Hi!
Maybe somebody faced it..
Issue:
Davinci gets error with opening project after adding back and forth short circuit expression link in fusion between custom tool node slider and transform node value center.
My attemps to fix:
1 restart mac os
2 open projects in different order
3 Open in Read Only Mode
4 Export Project... Import Project...

So, issue solved, but it is not short foggy way to get few second more for delete remove corrupted sequence and resave project (I tried and did it only one time successfully):

Export Project… copy Import Project…

Restart mac os in safety mode (with pressed shift) – it is impossible to open Davinci & because you can’t use GPU in safety mode

Add & change for random location in Media Storage Locations preference

Decrease Memory Configuration to minimum

Change GPU to OPEN CL

Restart mac os in normal mode

After these steps I can open new imported project ( maybe for 7 seconds before DaVinci error), clear bad seconds and resave it. Now it works.)…!!!

I cant’t repeat open corrupted project(..

So, maybe the steps forced rebuild Davinci’s project condition(I don’t know 8(0) ) and give me the necessary time.
