Self-Diagnosis

Before creating an issue, take some time to search these resources for an answer. It's possible that someone else has already seen and solved your issue.

• old NERDTree issues
• NERDTree documentation - :h NERDTree
• NERDTree Wiki
• Other resources: https://stackoverflow.com, https://vi.stackexchange.com, etc.
• I reviewed Error detected while processing function nerdtree#ui_glue#invokeKeyMap[1]..76[18]..75[3]..<SNR>33_customOpenFile[1]..105[1]..1 21[3]..177[6]..178[17]..13: #1347 and NERDTree.TreeNotOpen thrown when opening Neovim into NERDTree #1408
  As you said, they are simillar up to the invokeKeyMap but then different in the details.

Environment

• Operating System: MacOS Sonoma v14.4
• Vim/Neovim version :version: vim: 9.1.0250; nvim: v0.9.5
• NERDTree version, found on first line of quickhelp ?: 7.1.2
• Plug 'preservim/nerdtree', { 'on': 'NERDTreeToggle' }
• Are you using any of these NERDTree-dependent plugins?
  • [xx ] Xuyuanp/nerdtree-git-plugin
  • ryanoasis/vim-devicons
  • tiagofumo/vim-nerdtree-syntax-highlight
  • scrooloose/nerdtree-project-plugin
  • PhilRunninger/nerdtree-buffer-ops
  • PhilRunninger/nerdtree-visual-selection
  • jistr/vim-nerdtree-tabs
  • Others (specify):
• Provide a minimal .vimrc file that will reproduce the issue.
  Sorry... I deleted a bunch of stuff, and trimmed down all the plugins to the absolute minimum. Error still occurs here as described below. If you want really MINIMAL, I'll work on that
  vimrc_MINIMAL.txt

Steps to Reproduce the Issue

1. Open a new vim with nerdtree
2. move down to a text file in the list
3. press 'i' to start editing the file

Current Behavior (Include screenshots where appropriate.)

Throws the error

Error detected while processing function nerdtree#ui_glue#invokeKeyMap[1]..96[18]..95[3]..<SNR>185_openHSplit[1]..125[1]..141[3]..197[6]..198[17]..33:
line    3:
E576: Error while reading ShaDa file: last entry specified that it occupies 48 bytes, but file ended earlier

and then continues.
The error is not repeated if I close and re-open the same file, but if I try to open any other file with 'i' I get the error.
Opening a file with 's' also throws the error.
Here's a video

Should quietly open the file.
