When @Callum or another Serif staff member gets back to this topic, they may have something they want. I don't have any further ideas at the moment; sorry.
I used the MSIX installers. The entire affinity suite has been installed on my system for quite some time now (new PC in June installed upon purchase of machine. I have been in Amsterdam for the last 5 days and the PC has been off but was working on the software the night before leaving for my trip and it was working fine). It is the first time I have encountered the issues.
There is no affinity software running in task manager for me to end. I booted up this evening to do some work and none of the V2 software works.
I have reinstalled V1 which works with no issues. Any other suggestions on what could be causing the issue?
What OS?
If Windows:
Have you installed using the EXE installers or the MSIX installers?
Have you verified via Task Manager that none of the Affinity V2 apps are running, and then started them one at a time, waiting until each has fully initialized before starting the next one?
