Hey @az-z, Thanks for filing this issue!

I've allocated some time toward tracing this bug, nerdtree-project-plugin is almost 10 years old at this point so there might be some incompatibility issue that we have introduced over the years and went unnoticed because of the low user base of the said plugin.

But fortunately, there is already a PR for this problem on the nerdtree-project-plugin which hasn't merged yet(it is from 2021), Can you use this version instead and report the result?

I'll close this issue since the problem originates from one of Nerdtree's plugins and doesn't have to do with Nerdtree itself. But I strongly believe that the fork mentioned above would fix the problem.
Feel free to reopen this issue or create a new one if there are any other problems even with this plugin excluded from your config.
