On my local Linux Mint 21, when I follow the steps
git clone --depth=10 --branch=master https://github.com/transmission-remote-gui/transgui.git .
git checkout -qf be92509c3cbad97ec2e131760a36eeda7a1410eb
and then use the build.sh script, I have no "Access Violation" errors.
The transgui executable and the txz-archive are built normally.

Btw, I have fpc version 3.2.2 and lazarus version 2.2.0, from standard Linux Mint repository.
