bootstrap.bundle.min.js is locked

I get an error message when compiling my newly crated bootstrap project
It says bootstrap.bundle.min.js is locked by an other process
But
I just started my Computer
then Started my delphi 13
then open my project
and the make a build
So no other program can have any interference with bootstrap.bundle.min.js

I have no idea where this might be coming from. Maybe the server you're using is locking this file. I suggest to restart your machine if you do not know what process it is.

If I restart my computer
the problem is still there when I start the project

At what exact stage do you get this error message and what app is triggering this error message?
Is this file bootstrap.bundle.min.js in your TMSWeb\Release output folder after you compile the app in release mode?

after a little testing
I deleted the file from my project file
I also deleted everything from TMSWeb/debug (no release at this time)
When building the file is recreated and in the end I get the message
It says C:\MicWeb\bootstrap.bundle.min.js is locked by an other process
C:\MicWeb is my project map I moved it outside my dropbox if it could have someting to do with that

If you deleted the file from your project and this file is still recreated in the TMSWeb/debug folder then either you look in the wrong folder or the file is still somehow added to the project. Our compiler will only copy files that are part of the project to the output folder.
