Flow displays errors, where there are none. Eg:
Restart with flow stop and flow wont help it.
If I close the file and reopen it, the errors disappear, but other errors appear as I continue coding.
My flow version:
"flow-bin": "^0.125.1"
Any ideas how I can get rid of these annoying errors?

Can be an issue with Flow LSP. Try unchecking
javascript.flow.use.lspin Registry (in Help | Find Action, typeRegistry...to locate it)
