If the SMTC feature is enabled (Preferences -> General -> Windows 10 | 11) it can trigger a crash due to a change in the build that was incorrectly applied. If the crash reporter is triggered then an updated copy of the plug-in will be obtained which should then resolve the issue the next time WACUP is run. The handling to pull down fixed plug-ins post-release is ironically broken so disabling the SMTC option is the best workaround until a newer build with the fix is made available.
There can be random crashes on closing depending on how many active folder monitor entries have been setup.
Some modern skins may not draw correctly with either partial or completely missing window frames or flashing elements. This seems to be due to a change made on Feb 20th in the interim / beta builds to resolve seeker bar elements along with some other elements not showing as expected in the skins. A solution to keep the prior fix & un-break the skins now being reported as broken is being looked into.
