Maybe exit IDE session, move all <user home>/.stm32* to some backup area then restart IDE back.

Let us know if helping.

CUbe:

C:\ST\STM32CubeIDE_1.5.1\STM32CubeIDE

Workspace:

C:\ST\workspace

workspace folder is empty. Do you mean move Cube ID folder?

[Cartu38 OpenDev]

None of them.

You have some STM32Cube extra metadata under your user home folder. all are prefixed '.stm'

If windows most of time 'c:\Users\<user name>\.stm*'

It is done. Sucess!

1. I found few folders with ".stm" prefix in  'c:\Users\<user name>\
2. and removed them. (summary about 500+mb)

And issue has gone!

You was write. Thank you!
