10s Lag every click

Hello,

I'm working on Davinci Resolve since 2 years, on the same computer (which is powerful enough) and I never had any problems. But since i work on Davinci Resolve 17, i have a big problem, i cannot work correctly.

Every time i click, or i do something (create a bin, move a clip, cut a clip etc etc) i have a 10sec freeze and it is very very annoying. it makes the workflow so slow and it is not possible to work.
I don't have this problem on the home PC, only on the portable.

Here are my specs :
Computer : MSI GS65 Stealth Thin 8RF-046FR
Windows 10-20H2
Intel(R) Core(TM) i7-8750H CPU @ 2.20GHz / 6 cores Turbo boost 4,1Ghz
GeForce GTX 1070 Max-Q 8GB
32GB Ram

I work on Davinci Resolve 17.1.1 Build 9
latest drivers installed, up to date.

I shoot with Blackmagic Pocket 4K in BRaw 5:1 to 8:1 and 12:1, i never had problems before, everything always have been smooth.

I Join here a log file if somebody can help me finding a solution it would really help me.
Thank you
