Huntsman v2 broken after last Synapse update

Hi, I own Huntsman V2 for a while now. Back in 2021 I had an issue with Synapse, when it updated I lost possibility to type on the keyboard. Disabling Synapse worked fine but I needed a fix. After long trial and error run with support I managed to somehow fix it by unistalling software, drivers, restarting PC and installing it again in a different directory. It worked fine until the recent update. Now the issue is back. It seems the new wersion of Synapse does not let me install it in a custom directory any more. Please help!
