Update
thank you for your care, my problem has now been solved through some steps I have taken
I have repaired my TM through the free app
I have reorganised my TB
I have carried out the necessary performance in my TM
and now my studio works the same as before, hope it will continue!
my guess for this issue is using a client's project and joining my TM with it at the same time, maybe or maybe not!
Thank you again
