Go fmt is running forever at Goland - intellij-idea

Question

I've installed the last version of Goland recently, but it's nevermind, because this bug is reproducible on 2020* versions too. I enabled two file watchers - gofmt and goimports as usual and it worked perfectly until today. I don't know what happened. I just see
Running file watcher "go fmt" or Running file watcher "go imports" at the bottom of the IDE and they run forever. Here the output of the IDE cmd:
OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.

I event tried completely remove all files under ~/.config/JetBrains/GoLand* also with no success. Tried to remove .idea folder under project with the same result.
Use Linux Mint 20.2.
