slow start/load

After musescore 4.00 I'm happy and all the things seems normal.

After de updat to 4.01 the programm load very slow. It takes a long time .

Then I start 4.00 again and it's a normal time before all the things are loaded..

Then I started 4.01 again.... it takes a much longer time before I see something.
The startup screen is in a normal time but then..I wait..I wait It takes 1 minut before I see te working page.
( one minut in a liftime is a split of a second but waiting on a program...... )
