Better minecraft(plus) use mantle for alot of mods so i cant remove it when i install it it crash the game with exit code 1i tried latest ver for 1.16.5 and the 1.6.152 ver but still crash

update:fixed it i removed mag and dynamic mod(on the modpack page

I am going to close this for lack of information. Never tell a mod author their mod is crashing without providing the crash report, there is nothing we can do without a crash report. Glad you solved it, but if you had not solved it already this issue gives me no information to help you.
