How do you able to play?

I usually can play from 1 sec to 2 mins without crash, does everyone live like that? Is there any temporary cure?

How good is your PC? Maybe try reducing all of your settings.
Validate files or try reinstalling might help.

- move any valued save games elsewhere
- "uninstall" in Steam-Vic3
- manually delete both the Steam/SteamApps/common/Victoria3 AND Documents/Paradox Interactive/Victoria3 folders - In particular make sure there are no files or folders left under either the Steam Victoria3 or Documents Victoria3 locations, before installing again
- re-install game in Steam, run a Steam Verify when done.
- add Victoria3.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list.

THEN
Right click on Victoria3.exe , properties, compatibility. Tick "disable fullScreen optimisations" untick every other box in that dialog, Apply and exit.
Then in the launcher Game Settings menu, select fullScreen display mode, Vsync off, cap refresh rate at 60.
