Wont let me Bake animation to Mixamo rig Blender 3.30

[Liam FPS]

HI

Im trying to bake an  animation to a mixamo rig.

I have uploaded my own character and downloaded multpe animations and blended them using the NLA

But it wont let me me bake the animations at all 

I have exhasuted every avenue and have reached my limit XD 

The error thrown out is 

Ive re made this animtion sequence over what feels like a million times

Python: Traceback (most recent call last):
File "C:\BLANK\AppData\Roaming\Blender Foundation\Blender\3.3\scripts\addons\mixamo_rig\mixamo_rig.py", line 260, in execute
_bake_anim(self)
File "C:\BLANK\AppData\Roaming\Blender Foundation\Blender\3.3\scripts\addons\mixamo_rig\mixamo_rig.py", line 2082, in _bake_anim
if act.frame_range[0] < fs:
AttributeError: 'NoneType' object has no attribute 'frame_range'

If any one could help i would be truly grateful, as i was planning on using more of these to help with a silly video i was hoping to make for someone

with out the files its impossible to test

i would need the base model in T pose and the animate file or are you just asking what 'NoneType' & 'frame_range' means?

HI, apologies if i wasnt clear enough !!!

Im very much a noivce when it comes to blender so apologies again.

my idea was to go from Running > Jump > stumble > thrown, i put them all into blender and succsefully edited them and blended the animations in the nla editor but it wouldnt let me back the animations to the running fbx.

Please let me know if this isnt the correct information you need.

thank you again

the Mixamo rig is the one at the back, the one in front is your Tpose... if i run the rig on the back one it works correct and bakes just fine so the only answer i can come up with is the workflow made used made the error

[Liam FPS]

oh ? did it work with all 4 animations combined ? or just the one ?

as i followed the steps correctly i feel like.

how did you copy the animation over to the rig did you use the nla ?

sorry if thats too many questions, im sure ive made a mistake down the line, im just wondering where 

[Ussnorway]

i tested T, throw and jump animations and while i wouldn't say it was perfect i think Blender does a fair job for free software

Did you figure it out, having the same issue/?

thx

[Liam FPS]

No, sadly not. It just wouldn't work. I haven't tried using an older
version of blender.

It wouldn't let me bake anything.
