Here it was solved by disabling IDE theming during the first run of the program right after the installation.

Go to Tools > Options > Theme Manager: uncheck "Enable IDE Theming".

I suspect it has to do with my use of 150% scale of text of the display settings under Windows 10.

hi,
after a clean un-install of RAD Studio 10.2.1, I installed the latest RAD Studio 10.2.3. At the end of the installation the program runs fine. After closing and restarting the application, the program opens with several messages of access violation in 'rtl250.bpl' and quits. Sending the error message details always fails with some xml-error. These are the error message details:

On my system there are 4 'vcl250.bpl' files:
C:\Program Files (x86)\Embarcadero\Studio\19.0\bin

C:\Program Files (x86)\Embarcadero\Studio\19.0\Redist\win64
10-03-2018 01:55 5.688.176 vcl250.bpl

I have repeatedly installed and un-installed the software, but the error keeps getting back.
I do hope that someone helps to solve this problem.
Thanks.
