how to fix ImportError: DLL load failed - python-3.x

Question

I am running Python 3.8 on Windows 10 Pro. I am attempting to fit a multinomial fixed effects model to some data. All the packages appear to load fine, the data loads and can be manipulated and viewed. But I get an error when I call a module that my collaborator wrote to fit the model (called contactai).
Here is the code for contactai:
Note: tt stands for theano.tensor and pm stands for pymc3
def fixed_effects_model(X, y):
Parameters
X : array contains covariates
Design matrix n x p
y : array or shared theano variable
Multinomial response variable, n x 3
Returns
pymc3 model object containing fitted model
yarray = y.eval()
else:
yarray = y
if type(X) == tt.sharedvar.TensorSharedVariable:
Xmat = X.eval()
else:
Xmat = X
model = pm.Model()
with model:
# Transformed coefficients
betaD = pm.Normal('betad', mu=0, sd=5, shape=(Xmat.shape[1], 1))
betaI = pm.Normal('betai', mu=0, sd=5, shape=(Xmat.shape[1], 1))
# Softmax transformation with no contact as baseline
etad = tt.exp(tt.dot(X, betaD))
etai = tt.exp(tt.dot(X, betaI))
p_d = etad / (1 + etad + etai)
p_i = etai / (1 + etad + etai)
p_n = 1 - p_d - p_i
ps = tt.stack([p_n, p_d, p_i], axis=1).reshape((len(yarray), 3)) # Stack column-wise
Y_obs = pm.Multinomial("Y_obs", n=1, p=ps, observed=y)
return(model)
When I call contaciai.py in my jupyter notebook using
test_mod = contactai.fixed_effects_model(Xmat1, Yres.values)
I get this error message:
ImportError Traceback (most recent call last)

My collaborator does not get this error when running identical code on their macbook so the issue is not with the code. I installed all packages with pip. Any help would be greatly appreciated, this has brought me to a standstill on this project.
