MPC not opening files

Since updating with klcp_update_1692_20220327.exe today my multimedia pc (Asus NP40) running Win11 does not open the mp4 files any longer. On doubleclick the mpc logo shows and after a few seconds it reverts back to the explorer window? It happended with various mp4 files the same way. When starting mpc and opening each individual file seperately it plays however as wonderful as ever? I reverted back by installing the mega K-Lite_Codec_Pack_1690_Mega.exe and hey presto everything is fine as always. Is there perhaps a bug with the update 1692?

Do you have the "launch files in fullscreen option enabled?" There is currently a bug with that option. There will be another update soon.

Yes, the option for full screen is enabled and has so far never given a problem. Thanks for the quick reply, will wait for the next update.
