I can also confirm that 2022.2.1.4 doesn't work. I downloaded/edited the PKGBUILD to change the version to 2022.2.1.5 and installed that version. Works fine for me so far.
This isn't an Arch related link, but it is the same experience I had with 2022.2.1.4 on Arch.

Support for this software (Remote Desktop Manager) should happen on their forum: https://forum.devolutions.net/product/rdm-linux
Issues with the packaging should be reported here.
