Weird behavior after loading sessions- crashes in neovim and disfunctional coc

[eyalk5]

Hi,

There is this weird behavior. While it is confirmed in my environment(which is an adaptation of yours based on a bit of an old version). I don't plan to try to have a minimal reproducible example as it would take hours.

I know that after loading session file using ctrlspace, I get strange errors all around. That is, I know that if I load a session, and then launch vimspector remotely on one of the python files - it crashes. It might be dependent on the session. I also have two crash dumps - in both of them I loaded the session and immediately afterward, I launched the debug session. when I just opened the file and then launched the debug session it worked.

There is another symptom. I used to load a "default" session at the start - on the vim load event. But afterwards, coc didn't work in most cases(but threw errors). It took me many hours to figure that out.

I wonder if you can guess about the cause(variables are saved between sessions?). And I'd appreciate it if anyone that has similar issues could comment. Thanks.

Did https://github.com/vim-ctrlspace/vim-ctrlspace/pull/268 change anything?

[eyalk5]

will check it someday. This would be a painful merge.
